For a lot less than a Monster Miata you can add a Jackson Racing supercharger kit and get up near 200hp in a 2100 lb car.  Here's mine:

It's a ton of fun (literally!)
Here's a video:

Actually, it's for sale if anyone's interested.

I respectfully disagree.  The 1400 and 800 Intruders are almost identical except for size.  Unless you know to look for a radiator (800/S50) instead of an oil cooler (1400/S83) or the different tail lights they can be hard to tell apart.  As the smaller of the two I think the 800 is a little closer to the Savage/S40.

OK, I can see that.

Wow, you guys must have friends that don't know how to ride, poor tune on their bikes, or are over weight. My buddys wife has an 08 S40. Its neat, light , and torquey-but it stands no chance against my 75 XLCH 1000 (451lbs, 67hp-68ft/lbs), my 98 1200 XLC (477lbs, 71hp-73ft/lbs), my 71 Bonnie chopper (287lbs 55hp, 42ft/lbs), or the 81 XJ650 (389lbs 51hp-32ft/lbs). All of them I race at the track, same with her S40. The S40 will walk the dog all over my another friends 2000 VT750 Shadow ACE, 33hp-37ft/lbs and weighs 527lbs! Her S40 is hitting 14.97 (best) to 15.15 (average). the Bonnie has a 12.8:1 first gear and takes off like a rocket. the 98 is hitting 12.73s all day long with open pipes (35" long) and chopped air cleaner, and a jet change (48 pilot, 180 main). thats the only deviation from stock. On the twisties, the only one that will hang with the S40 coming outta the turns is the Yamaha. Its got decent brakes, unlike every HD-save for the buells....
I have grown fond of that little single though. I added an open fishtail pipe (have put a small baffle in it though), does anyone make an ignition upgrade for it?? I wish the advabce came on a little sooner. And do these things have a rev limiter?? I've heard that you can screw up the timing by high/over revving...true??

I believe Ed L did it. IIRC he said it was more trouble than it was worth.

how about a 280 lb 700 Savage pushing 55-60 hp...  a friend has a dyno in his shop and is ready to run the numbers; we shall see if the time and $$ has been worth it very soon.

My apologies!  I posted a wrong 1/4 mile time for the S50 in an earlier post.  It should have been 13.3 rather than 12.3.  Even though that's a significant difference it doesn't change anything else I said about it except that it's not quicker than the H-D's except for the 883.
